The paper presents a complete risk assessment system of urban natural gas network from seven modules. Pipeline hazard scenarios are analyzed and the reasons for seven modules risk assessment system model are presented. Based on objective data of various pipeline sections, the assessment system also allows sections of pipeline to be ranked into a risk hierarchy by using advanced scientific mathematical treatment methods. The system is displayed in geographic information system (GIS) platform, in order to implement data resource sharing and visualization of assessment results. Therefore, the dynamic and safety management of gas pipeline network is achieved and the safe and reliable operation of urban gas pipeline network can be ensured. An application based on a real case study was undertaken so that the effectiveness of the assessment system could be verified.
